如何在不使用print语句的情况下在Python中显示没有索引的选定列

import sys

data = [
    [1, 'John', 'Doe'],
    [2, 'Jane', 'Smith'],
    [3, 'Bob', 'Johnson']
]

selected_column = [row[1] for row in data]  # 选择第二列

output = '\n'.join(selected_column)
sys.stdout.write(output)

import sys

data = [
    [1, 'John', 'Doe'],
    [2, 'Jane', 'Smith'],
    [3, 'Bob', 'Johnson']
]

selected_column = (row[1] for row in data)  # 选择第二列

output = '\n'.join(selected_column)
sys.stdout.write(output)
